Wheel Cutter
The wheel cutter is a valuable addition to the lathe. Several different styles of these tools are made, each possessing points of merit. They are designed for cutting all kinds of wheels and pinions used in key and stem-wind watches. When the cutter spindle is vertical the belt runs directly to it from the countershaft, but when horizontal the belt passes over idler pulleys held above the lathe. These idler pulleys are also used to run the pivot polisher. Fig. 316 illustrates the American Watch Tool Company's wheel cutter.
